SPECIFICATION forming part of Letters Patent No. 588, 503, dated August17, 1897.

Application filed March 2 9, 1 8 9 7.

flerial No. 629,736 (roman T0 aZZ whom, it may concern.-

Be it known that I, SIMON H. STUPAKOFF, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented or discovered certain new and usefulImprovements in Detector-Rails, of which improvements the following is aspecification.

The invention described herein relates to certain improvements in clampswhereby detector-bars may be secured to the rails in proper relation tothe switch-points It is very frequently necessary to arrange thedetector-rails on the main rail, against which the movable rail of theswitch bears in one of, its positions; The hook-bolts heretofore usedfor this purpose necessitated the notching of the flange-rail for thereception of the hooks in order to place the detector-rail in properrelation to the switch-point and at the same time permit of the requiredmovement of the switch-rail.

The object of my invention is to provide means whereby the detector-railsupport can be secured to the main rail without any notching or cuttingof its flange, such notching or cutting being objectionable on accountof its weakening efiect.

In general terms the invention consists in the construction andcombination substantially as hereinafterfmorc fully described andclaimed. p v

In the accompanying drawings, forming a part of this specification,Figure 1 is a side elevation of a rail having a detector-bar attachedthereto by my improved support. Fig. 2 is a similar view illustrating amodification in the manner of securing the supporting-bracket to therail-flange. Fig. 3 is a transverse section, the plane of section beingindicated by the line III III, Fig. 2. Fig. 4 is a similar View, theplane of section being indicated by the line IV IV, Fig. 1. Fig. 5 is aperspective View of the supportingbracket. Fig. 6 is a similar View ofthe bracket-clamp, and Fig. 7 is a sectional elevation of thebracket-clamp.

In the practice'of my invention the detector rail or bar 1 is pivotall yconnected to the upper ends of a series of two or more arms 2, whichhave their lower ends loosely mounted upon pins 3, supported uponsuitable bearings in the brackets 4. The brackets 4 are formed, asclearly shown in Fig. 5, with semitubular lips 5 and by preference witha bracing-lip 6 intermediate of the semitubular lips 5. These lips areadapted to pass under the flange of the rail, while lugs 7, also formedintegral with the bracket and alternating with the lips, pass over thetop of the rail-flange. Each of these brackets is provided with anangular arm 8, which has a bearing 9 at its. outer end for the receptionof the supporting-pin 3 of the arm 2. A second bearing for the inner endof the pin 3 is formed in the body portion of the bracket, as shown inFig. 7. These brackets may be secured to the rail either by hook-bolts,which pass through the tubular lips 5, as clearly shown in Figs. 1 and4:, or the brackets may be secured in position where there isnotsufficient room to employ hook-bolts by means of clamps 10. Theseclamps are provided with downwardly-projecting tubular flanges 11,adapted to pass over the outer ends of the semitubular lips 5, as shownin Figs. 2 and 3. Intermediate and to one side of the flanges 11 isformed an upwardly-projecting arm 12, adapted to bear against the web ofthe rail and be secured thereto by means of a bolt 12. It will beobserved that by the employment of this clamp the inner edges of therail-flange are left unobstructed and the flange is in no wise weakened,as by notchingl In order to support the detector-bar when in lowered ornormal position, suitable stops are secured to the rail or to the clamp10. \rVhen it is desired to employ stops independent of thedetector-rail support and where there is suflicient room for theemployment of hook-bolts, a bracket adapted to fit over the edge of therail-flange is secured to the rail by a hook-bolt 14. This bracket isprovided with an arm 15, adapted to carry the detector-rail stop 16.This stop or finger 16 is preferably so attached to the arm 15 as to becapable of vertical adjustment. This means of adjustment consists inslotting the stop or finger 16 for the passage of a clamping-bolt 17, asshown in Figs. 1 and 4. In

order to prevent any accidental displacement of the finger or stop fromits adjusted position, it is preferred to form the bearing-surfaces ofthe arm 15 and the stop with opposite inclinations, as clearly shown inFig. 4, so that after the stop or finger has been clamped in positionany blow on its upper end will result in wedging it more firmly inposition. The stop is formed with a fiat unconfined or unbounded top orbearing surface, so that in case cinder,stone,orother objects shouldlodge thereon the latter can be readily knocked off or displaced by thedetector rail or bar in dropping to its normal position.

hen by reason of the location of the detector-rail hook-bolts cannot beemployed for securing the stop in position, the stop 16 is formedintegral with a plate 18, adapted to be bolted to the web of the rail,as shown in Fig. 1. In lieu of securing the finger or stop 16 integrallywith the plate 18 it may be adjustably mounted thereon, as shown in Fig.2.

\Vhen the clamps 10 are employed for holding the brackets 4 in position,the stops for the detector-rail may be formed integral therewith, asshown at 16, or adjustably mounted thereon, as shown at 16.

By reason of the construction and relative arrangement of the lips andlugs 7 0f the bracket a the same can be produced by casting in a moldwithout the use of cores. This is an important feature, as this methodof manufacturing the brackets greatly reduces the cost of the same.

I claim herein as my invention 1. A bracket for supportingdetector-rails, the combination of semitubularlips and lugs arrangedalternately and respectively adapted to pass below and above therail-flange,

with bearings for the pin or shaft supporting the rail-carrying arms,substantially as set forth.

2. The combination of a bracket constructed to engage the edge of arail-flange and provided with bearings for the pin or shaft supportingthe rail-carrying arms, in combination with a clamp adapted to besecured to the Web of the rail and to engage projections on thesupporting-bracket, substantially as set forth.

3. The combination of a bracket provided with alternating lips and lugsarranged to pass respectively below and above the rail flange, a clampprovided with flanges adapted to overlap the lips on the bracket, and tobe secured to the web of the rail, and a detector bar or rail movablymounted on the bracket, substantially as set forth.

4.. The combination of a bracket adapted to be secured to the flange ofa rail, a detector.- bar pivotally mounted on the bracket, astopindependent of the detector-bar support, and having a plain unconfinedor unbounded bearing-surface for the detector-rail and means forclamping the stop to the rail, substantially as set forth.

5. The combination of a bracket adapted to be secured to the flange of arail. a detectorbar pivotally mounted on the bracket, a clamp and a stopadjustably mounted on the clamp, substantially as set forth.

In testimony whereof I have hereunto set my hand.
